Beit known that I, SEVERN WINBERG, av citizen ofthe United Statesnesiding at Galesburg, vin the county of Knox and State of Illinois,

have invented-certain new and useful Improve.-

-ments inSpirit-Levelsand Plumbs of which the following is a speciiication. A v

larly vto that specific typeor class ofthe same'l known as gravitylevels and plumbs.

It further relates toanimprovement on 1902, onspirit-leveland plumb.

Thekobjects of my presentinvention are,l

primarily, to` overcome dilcultieswith which I have met in the use and practice of lmy aforesaid patented' invention and especially kin the adjustment thereof;

with this and other objects@ viewthen-g vention consists in the novel construction and i combination of parts,4 all as hereinafter de` scribed, and

In the accompanying drawings, which are .made a part .of this specification, similar letters of .reference ,refer to like parts in the different figures thereof, and in which- Figure lis a plan elevation showing the pointed `outin the' appended glass-containing cylinder is formed; Fig. 8,..

the blank rolled up into shape, partly broken away; Fig. 9, the cylinder-cap.

As hereinbefore stated, I have met with faults and difliculties in the use and practice of the device shown, described, and claimed in the use of my aforesaid patent. One and perhaps the chief of these faults was in the -adjustment of the level tube or glass and its containing-cylinder, owing to the following: When used when and where there is much moisture, the stock is liable to become warped by expansion or contraction, thereby throwing the level-glass and its containing-cylinder out of plumb or adjustment. In such case'it was necessary in my prior device to remove two parts in order to gain access tothe adjusting-screw. It was also necessary to have a screw-driver or some other tool by which the parts might be adjusted. 4 Inmy present invention it is unnecessary-` to remove any part, thus' saving a great deal of time; neither lis any tool needed to make the adjustment, asy

willbe hereinafter described.

For the purposes of this invention-"it `will be .unnecessary to describe any more'thereof than those parts which relate thereto. I

I represents a levelstock'; D, a 1Aframe in an opening I therein; '(1, an' adjusting-wheel threadedwon'forrthe purpose of adjusting, limiting, and regulating the movementof the plate A; A, a level-'tube-containing cylinder` orcapsule having an opening A? and having studs or journalE E', integral therewith, pro- `particularly jecting fromv its outer end and at or near its peripheryand VA2 a level glass or tube within said cylinder or capsule.

Vinternally thereof, and its threaded end pro'- `rjects through oneof said openings, `as shown best at Figs. L and 6. The stud or journal E is seatedin a bearingA4, Fig. 6, in the plate A near its mid-length. and the stud or journal E is seatedin a suitable bearing in the distal end of the frame. v. D2 is adisk or plate iixed to the stock A'by screws A to partly cover the opening I and hold or retain the frame in place thereinand has an opening F', through which access may be had to the roughened', milled, or notched periphery of the wheel C, and also has a latch or cover F hinged or pivoted thereto,

which latch -may have a detent on its under side to engage with the slot F and prevent accidental displacement of the adjustingwheel. The latch further serves to prevent dust or dirt entering through the slot and clogging or interfering with the operation of the device. Another disk or retaining plate (not shown) is secured' to the stock on its reverse side also for holding or retaining the' frame therein. The wheel is held from sidewise or lateral movement partly by a slot D3- 'Fhe plate A is seated in slots or openings D in the frame IOO in the frame, partly by a slot D4 in the levelstock, and partly by a slot F' in the disk D2. Thus held the Wheel C acts as and performs the functions of a nut into which the end of the plate A is threaded.

When it is desired to adjust the stud or journal E, and thereby the proximal' end of the cylinder and level-glass, the operator by revolving the Wheel C with his thumb or linger will cause the plate, and thereby the last aforesaid parts, to be drawn or thrust in one direction, and by reversing the direction of revolution of the Wheel the direction of movement of said parts will be reversed and a ready and positive adjustment of said parts thus effected.

G is a blank from which the cylinder or capsule is partially formed. After it is rolled up into cylindrical form and its edges soldered together the level-tube is placed therein and a disk or cap H is loosely soldered in either end of the cylinder. Should it be desirable to remove one of these caps, a knife-blade or other sharp-pointed instrument may be inserted at its periphery and pressed outward, When the cap Will fall out.

Without limiting myself to the details of construction and arrangement shown, I claim- 1. In a spirit-level, and in combination, a level-stock having an opening therein, a frame resting therein, a cylinder Within said frame, journals at the ends of said cylinder, a levelglass contained Within said cylinder, slots in the frame, an adjustable plate carried by the frame to move in said slots, said plate having one of its ends threaded and having a bearing in which one of said journals is seated, a bearing in the distal end of the frame, in Which the other of said journals is seated, and a Wheel threaded on the threaded end of the plate, substantially as described and for the purpose specitied.

2. In a spirit-level and in combination, a level-stock having an opening therein, a frame Within said opening, a level-tube-containing cylinder, journals integral with said cylinder and at the ends and at or ynear the periphery thereof, a level-glass Within the cylinder, slots in the frame and an adjusting-plate seated in said slots, one end of the adjusting-plate being threaded, a bearing in said plate, in which one of the journals is seated, a bearingin the frame, in which the other of said journals is seated, another slot in the frame, a slot in the level-stock, a Wheel resting in and held from lateral displacement by said slots, said wheel threaded on the threaded end of the plate for adjusting it and thereby the proximal end of the cylinder in higher or lower positions, substantially as described.

3. In a level, the combination of a stock I, a frame D, a cylinder having journals E, E, a level-glass within said cylinder, slots D in said frame, a plate A seated in said slots, one end of said plate being threaded and extended beyond the frame, a bearing in said plate, a wheel C threaded onto the extended end of the plate for the purpose described, a bearing in the frame, a retaining-disk, aslot therein, and a latch thereon, all substantially as described and for the purpose speeiiied.

l'. In a level and in combination, a frame, an adjustable plate partly Within said frame and having a threaded end, slots in said trame in Which the plate is carried, a Wheel partly Within said frame, said wheel being threaded onto the threaded end of the plate, a bearing in the frame, a bearing in the plate, and a level-tubc-containing cylinder seated in said bearings, substantially as described.

5. In a spirit-level, and in combination, a stock, a cylinder containing a level-tube, an adjustable plate having a bearing in which one end of said cylinderis journaled, one end of the plate being threaded, a wheel in threaded engagement with the adjustable plate, a frame, a bearing in said frame, in which the other end of the cylinder is journaled, and plates for retaining said parts in place within the stock, substantially as described.
